CHARLES G. CONN, OF ELKHART, INDIANA.

CORNET.

SPECIFICATION forming part of Letters Patent; No. 295,981, dated April 1, 1884.

Application filed July 14, 18834 (No modcLl To all who/'lt it may con/cern,.-

Be it known that I, CHARLES G. CONN, a citizen of the United States, residing at Elkhart, in the county of Elkhart and State of -Indiana, have invented certain new and useful Improvements in Cornets, of which the following is a specication.

My invention relates to the connectingpipes between the valves of a cornet; and it consists in making said connecting-pipes of curved or bent form, with the result of giving the airpassage more regularity and avoiding the sharp steps or corners present in the old style pipe.

In order that my invention maybe more fully understood, I will proceed'to describe it with reference to the accompanying drawings, in which- Figure l is an elevation of a portion of the 2o front side of a cornet embodying my improve ment. Fig. 2 is a section of the same longitudinally of the valve-cylinders.

The cornet is constructed with customary air-pipe,A,valve-bends B, and valve-cylinders l 2 3. Connecting the valve-cylinders are pipes D, curved, as shown, so as to present at the points d d an obtuse angle. Sharp angles in the wind-passage are thus lessened, and the wind consequently less broken in its passage therethrough.

I am aware that it'has been .proposed` to lessen the abrupt angles in the air-passage by curving the connecting-pipesin planes at right angles to the plane of the valves; vbut inasmuch as the piston-passages in a cornet or piston are necessarily made on lines inclined to the axis, and consequently traverse the pistons somewhat longitudinally and in the plane of the valves, it is obvious that that curve of the connecting-pipe which shall least interrupt the liow of air should continue the curve of' the piston-passages in the same plane.

Having thus described my invention, the following is what I claim as new therein and desire to secure by Letters Patent:

In a cornet, the conn nectingpipes D between the valves, curved or bent in the plane of the valves, as and for the purposes set forth.
